VEHICLE MOTOROOLING DEVICE.

Specification of Letters Patent.

Be it known that IQBENJAMIN C. Lonnie,

acitizen of the United States, residing at the town of Cranston, in thecounty oflrovidence and State of Rhode Island have 1n\'*ented-certainnew and'use'ful Improve-g ments in Vehicle-Motor-Cooling Devices, of

which the following is a specification, refer-' ence being had thereinto the acoompanylng drawing..-

T his invention relates to an improved cooling device for automobileengines and has for 1ts-ob ect to provide slmple and effective meanswhereby the air may be caused to circulate rapidly around. all of theengine cylinders and so prevent the same from overheating.

In carrying out myinvent-ion I provide a cooling device comprising ahousing or casing about thelengine whose sides taper to'- ward thefront, which form materially reduces the windage or frictionalresistance in forcing avehicle [rjipidly through the air. [D

In using a taperin casing on. an air cooled engine the air is readilyforced-in aroundall of'the cylinders to carry off the generated heat.

Another feature of my invention is that in the use of water cooledengines this tapering portion of the casing may be used as a radiatorthrough which thewater .is forced from one end to the other forming anextensive radiating surface wherein the water may be effectually cooledbefore it is carriedagain around the cylinders.

A ra diator of my improved form serves to conduct the air through theradiator and direct the same around all of the engine cylinders thereby.forming another means in addition to'the water for cooling the enginecylinders.

in vehicles such as automobiles of the most recent construction whereina plurality of cylinders are used the same arep'referably set at theforward end of the car one after the other lengthwise of the same; Thecasing which covers or surrounds the engine usually with a gratingthrough which the air enters to cool the cylinders. With thisarrangement it is obvious that the first cylinder re- .ceives thegreatest benefit from the cool air. entering through the grating, thesecond cylinder rece iving the heated air which passes the firstcylinder, and so on until the last.

has a square front portion provided cylinder receives but little benefitfrom. such an arrangement. Bythe use of my improved form of casing thisdifficulty is en:

tirel y obviated, the air is caught by the preectn g wings or vaneson-the sides of the tapering casing and is conveyed to all of thecylinders equally, thereby making the last I cylinder as cool-.asthefirst.

With theseand other-ob]ects in view, tl'1ej inventlon consists ofcertainnovel features of construction, as will be'more fully de-J scribed andparticularly'pointed.out in the appended claims.

lnthe accompany ng drawings:v Figure '1 is a top View of the bodyportion of a racing automobile with the upper portion or top of thecasing removed exposing the ends of the radiator tubes, also showing thestraight sides of the hood portion in section andfillustrating theaction of the air' on the cylinders as it passes through the vanes insaid casing. Fig. 2-is a side elevation of the casing-showing thetapering radiatmg surface of the same. Fig. 3-is an enlarge detail of athin flattened radiatorwater'pipe which is located in the taperingcasing, and

also showing an outwardly projecting plate.

which catches the air and directs thesame through the radiator onto theengine. leferringto the drawings at 1 is the body portion of anautomobile, which may be made in any desired form. At 22 are'the enginecylinders located'in the'forward end of the car, the same being inclosedby' the casing or housing 3. By casing I mean all of that covering whichincloses the motor, including the forward or tapering part in which isset the hollow vanes for-the water to circulate through, which part isordinarily'known as the radiator, and also the removable portion-back ofthat which. is commonly called the hood. At 4% are the tapering sides ofthe'hood which are shown as being brought together substantially to anedge-5 1n the front, but I do not confine myself. to this constructionas these tapering sides may terminate in a flattened portion at the.front or round nicely about the forward cylinder if desired. It'will beseen that the tapered portion of these sides reach well back around aportion of the engine, and the same'are provided with apertures 7-7 seton an angle so as'to direct the air Patented Feb. 17,. 1911.-

which the heated water is causedto circulate to be cooled, thin fiatpipes are U vanes of any style may be used.

In the ordinary. radiator, which is set square across the front, it isdiflicult to obtain suflicient surface to cool the water of anfordinary.. engine on a hotday, or to keep the water of aracingmachinebelow the boiling point in weather of-anyordinary temper ature, but bymy iniproved'construction the radiating surface is increased to morethan.

double its ordinary 'capacity'whereby the temperature of the water maybe nicely con-1 trolled.' This increase beyond the ordina capacity forcoolin is due'to the fact that I have provided com ined waterconduitsandair converging vanes so that the'o'ne mecha- 4 lterior of thevanes 13 provides for the circulation ides of said vanes are not onlypresented to insure the most rapid cooling action of air upon the sides'of said vanes or conduits so as'to cool the water therein, but alsoconcentrate or converge theaair upon the sides, of

the series of engine cylinders.

. In sumniing upthe advantages, by my improved construction the .aircooled engine, which has heretofore. given a great'deal of. trouble byoverheating, becomes thoroughly cooled, .th'us oflering a-simple andpractical solution of what has heretofore been considered'a difficultproblem. Then again, in the watercooled engine the radiator is providedwith a greatly increased area whereby the temperature of the same may bebrought as 'low as desired, and at the same time the circulation of airis increased around the cylinders, which greatly assists in'cooling thesame. v

In the construction of a ,casing for either style of engine it is foundof greatadvantage in addition to the circulationof air 85 throughthehood to have the side walls of thesame converge in order to reducethe resistance in forcing a car rapidly through the air, which isa veryimportant feature, es-

driven at a rapid-rate of speed.

The preferred construction is, as shown in the drawings, such that theseries of vertical conduit, vanes 13 which are flattened in cross-section,-present a. tapering formation with the conduit vanes on oneside inclined outwardly and to the right,- those on the othersides'being inclined, outwardly to the left, thereby providing in thebest manner for the double cooling function hereinbcforc de- IOOscribed. I

Having 'thusdescribed my in ention, what IcIaim as new and desire tosecure by Letters Patent, is: a 1. A cooling device for automobilescomprising a series of vertical conduit. vanes 'flattened in crosssection and arranged in tapering formation, the vanes on one side beinginclined outwardly to the right and those on the, other side beinginclined outwardly to the left. 1

2. A cooling device for automobiles comprising' a series of verticalconduit vanes flattened in cross section and arranged in taperingformation, the va'nes'on one side being inclined outwardly to the rightand those on the other side being inclined outwardly to the left,-- thesaid vanes having thin metal portions projecting forwardly beyond theconduit portions.
